Abstract (en)
The system has a fresh air feed pipe (10) split between a first pipe (14) with output into the vehicle interior (H) via air vents (18) and a second pipe (16) in which is placed an heat exchanger (20) for air heating with output into the interior (H) via hot air outlets (24,26,28). An adjustable shutter (34) is fitted in the first pipe (14) so as to regulate the flow of air. A fresh air duct (30) behind the shutter (34) connects the first pipe (14) with the second pipe (16) behind the heat exchanger (20). The fresh air duct (30) contains a wall (54), in the shape of a chicane projecting in the direction of the heat exchanger (2), which is designed to deviate the fresh air flow (F2) along the heat exchanger (20) surface so that the fresh air is heated before it exits through at least one of the outlet (24,26,28). The outlet (24) supplies hot air to the feet of front passengers and the outlet (26) supplies hot air to the feet of rear seat passengers whilst the outlet (28) is used for demisting and deicing purposes.
